Objective To explore the somatotype classification of high level dorsal muscle strength. Methods Dorsal muscle strength of a complete training unit of 418 male soldiers, according to the provisions of GJB1337-92 were measured and classified the somatotype by the method of Heath-Carter. Results The mean value of dorsal muscle strength of the 418 male soldiers was (134.3±22.6) kg, overall evaluation was good. Dorsal muscle strength good and above was 270, accounting for 64.7%; the mean value was (147.0±16.7) kg, the mean value of somatotype was 2.4(0.8)-5.0(1.2)-2.3(0.9), somatotype attitudinal mean（SAM）was 1.5, 87.8% focused on the medium of embryo type. The factors of endomorphy, mesomorphy and ectomorphy were the main factors that affected the dorsal muscle strength score. The better of the dorsal muscle strength score, the lower value of the endomorphy and ectomorphy factors, the higher value of the mesomorphy factor. Conclusion The high level of dorsal muscle strength in the somatotype classification is highly concentrated in the medium of the embryo type. Dorsal muscle strength is significantly positively correlated with the mesomorphy value.
